Abstract
Provided herein is a plunger assembly for advancing a plunger through a barrel, such as the barrel of a pre-filled syringe. The plunger assembly includes a stopper adapter defining an aperture. The stopper adapter includes a first restraining member adjacent to the aperture. The plunger assembly also includes a plunger rod having a first end, a second end, and a plunger rod head disposed adjacent the first end of the plunger rod. The plunger rod head includes a second restraining member engageable with the first restraining member of the stopper adapter. The plunger assembly is configured such that as the plunger rod head is moved axially within the aperture of the stopper adapter, the first restraining member of the stopper adapter engages the second restraining member of the plunger rod head to secure the plunger rod head within the aperture. A syringe assembly with a plunger assembly is also disclosed.
